Facile Synthesis, Structural, Morphological and Electrochemical Properties of Bismuth Sulfide (Bi₂S₃) Nanostructures.

Bismuth sulfide (Bi₂S₃) nanowires were synthesized successfully by a facile sonochemical method from Bi(DTC)₃ as a single source precursor. The structural, vibrational, morphological properties and the functional groups of the samples were confirmed by powder X-ray diffraction (XRD), Fourier transform infrared (FT-IR), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) analysis and Raman spectroscopy techniques. The formation of pure phase of Bi₂S₃ and nanowires like morphology was confirmed by powder XRD and SEM analysis. The purity and elemental composition of Bi₂S₃ nanowires were confirmed by EDX analysis. The electrochemical properties of Catechol (CC) at the modified electrode were studied with the presence of Bi2S₃ nanowires modified GCE electrode in aqueous solution with different scan rate and concentration. A novel method for determination of catechol using cyclic voltammetry (CV) was investigated. The homogeneous rate constants were estimated by comparing the experimental CV responses with the digital simulated results.
